The tissue extract (TTE) of a marine snail Telescopium telescopium, collected from the coastal regions of West Bengal, India, was extensively screened for pharmacological and biochemical properties. Telescopium telescopium (TTE) produced significant lysis of washed rat erythrocytes (both direct and indirect), produced haemorrhagic lesions in the skin and also released haemoglobin (in vitro tissue damage) from different tissue samples. TTE was found to produce pro-inflammatory effects when injected into the rat hind paw and also increased peritoneal vascular permeability. Furthermore, intravenous administration of TTE produced a decrease in blood pressure (hypotensive effect) in anaesthetized rats. The extract produced potent esterase activity, as was evident from the breakdown of FDA with subsequent release of fluorescein (in vitro). TTE also demonstrated prominent cholinesterase, phospholipase, phosphatase and protease activities.

It has been reported that clonidine is $\alpha_2$-adrenergic agonist, potnet new hypotensive drug in human with low dose. The change in blood pressure is implicated in the concentration, release, uptake and metabalism of catecholamine and activity of catecholamine synthesizing enzyme in specific brain areas. Thus the experiment was set up to investigate the effect on the enzyme activity of clonidine alone and that of clonidine pretreated with imipramine or tranylcypromine by measuring activity of the Dopa-forming enzyme, tyrosine hydroxylase (TH) and epinephrine forming enzyme, phenylethanolamine-N-methyl transferase (PNMT) in brain and adrenal gland. The TH activity in brainstem and substantia nigra is decreased by intraperitoneally administered clonidine 0.1mg/kg twice a day for 5 days, but increased in the rats pretreated with imipramine 10mg/kg intraperitoneally given 26 hrs and 5 hrs before decaptitation. However the TH activity in all regions of brain is increased in rats pretreated with tranylcypromine 10mg/kg intraperitoneally twice a day for 5 days. The effect of clonidine on TH activity is due to inhibition release of norepinephrine by activation of presynaptic $\alpha_2$-adrenoreceptor, axon terminal result in the decrease of TH activity in brain. The increasing of TH activity in brain results in attenuation of the role of clonidine by pretreated with imipramine or tranylcypromine in rats. The activity of PNMT was not significantly affected by clonidine, imipramine and tranylcypromine in adrenal gland.

Moraceae comprise a large family of sixty genera and neary 1,400 specieses, including important groups such as Artocarpus, Morus, and Ficus. In particular, Morus(mulberry) is a small genus of tree and shrubs found in temperate and subtropical regions of the Northern hemishere and has been widely cultivated in China and Korea, In addition, the root bark of mulberry tree have been used as an antiphlogic, diuretic, and expectorant in white medicine, and the crude drug is known as "Sangbaikpi" in Korea. Recently, some papers have been published reporting the hypotensive effect, antiviral effect, antifungal effect, inhibitory effect of cAMP-phosphodiesterase, and anticancer effect of this extract. Little is known about that Cortex mori could have been an antiallergic effect. The purpose of this study was the development of an antiallergic agent with an antiallergic effect from Cortex mori. For this, several in vivo and in vitro experimental models were used. Results are 1) Cortex mori inhibited the compound 48/80-induced degranu-lation, histamine release and calcium uptake of rat peritoneal mast cells, 2) compound 48/80-induced anaphylactic shock and cutaneous reaction were significantly inhibited by pretreatment of Cortex mori, and 3) Cortex mori inhibited the ovalbumin-induced late astmatic reaction. From the above results it is suggested that Cortex mori has some substances with an antiallergic activity. Our final purpose of this study is to develope the new drug with an antiallergic activity from Cortex mori

Objectives: Safranal is a pharmacologically active component of saffron and is responsible for the unique aroma of saffron. The hypotensive effect of safranal has been shown in previous studies. This study evaluates the mechanism for the vasodilatory effects induced by safranal on isolated rat aortas. Methods: To study the vasodilatory effects of safranal (0.2, 0.4 and 0.8 mM), we contracted isolated rat thoracic aorta rings by using $10^{-6}-M$ phenylephrine (PE) or 80-mM KCl. Dimethyl sulfoxide (DMSO) was used as a control. The vasodilatory effect of safranal was also evaluated both on intact and denuded endothelium aortic rings. Furthermore, to study the role of nitric oxide and prostacyclin in the relaxation induced by safranal, we incubated the aortic rings by using L-NAME ($10^{-6}M$) or indomethacin ($10^{-5}M$), each for 20 minutes. Results: Safranal induced relaxation in endothelium-intact aortic rings precontracted by using PE or KCl in a concentration-dependent manner, with a maximum relaxation of more than 100%. The relaxant activity of safranal was not eliminated by incubating the aortic rings with L-NAME ($EC_{50}=0.29$ vs. $EC_{50}=0.43$) or with indomethacin ($EC_{50}=0.29$ vs. $EC_{50}=0.35$), where $EC_{50}$ is the half maximal effective concentration. Also, the vasodilatory activity of safranal was not modified by endothelial removal. Conclusion: This study indicated that relaxant activity of safranal is mediated predominantly through an endothelium-independent mechanism.

Cortex Mori (Moros alba L.), the root bark of mulberry tree has been used as an autiphlogistic, diuretic and expectorant in herval medicine. Recently, a few papers reported that phenolic extract of Cortex Mori had the hypotensive, hypoglycemic, antiviral and anticancer effects, and hot water extract of Cortex Mori(CM) had inhibitory effect on the degranulation and histamine release from activated mast cells. These previous studies suggest a possibility that CM has an antidotal activity against inflammation which was mediated mainly by macrophage-secreting inflammatory factors. This study was performed to evaluate the influences of CM on carrageenan-induced edema in vivo and release of inflammatory mediators such as NO, TNF and IL-1 by macrophages stimulated with LPS or $IFN-{\gamma}$ in vitro. Subcutaneous injections of carrageenan into the mouse paw rapidly induced local edema by increasing vascular permeability, but single intraperitoneal injection of CM extract at 30 minutes before carrageenan suppressed the development of edema. NO and TNF production from macrophage stimulated by LPS or $IFN-{\gamma}$ were significantly suppressed, especially TNF secretion by up to 3-4 folds. LPS stimulated IL-1 production was also inhibited, but not significantly. Cell viability assay verified that the inhibition was not due to general cell toxicity. These results suggest that reduction of NO, TNF and IL-1 production may be one of the means by which CM prevent inflammation associated diseases.

Purpose: The purpose of this study was to evaluate the effects of inhaled clary sage (Salvia sclarea L.) oil or linalyl acetate on patients' anxiety and stress levels before undergoing chemotherapy. Methods: Forty-five eligible participants were randomly assigned to inhale clary sage oil, or linalyl acetate, each at concentrations of 5% vol/vol in almond oil or pure almond oil (control). State-trait anxiety inventory (STAI), Stress rating scale, anxiety-visual analog scale (Anxiety-VAS), stress-visual analog scale (Stress-VAS), blood pressure, and heart rate were measured before and after the inhalation prior to undergoing chemotherapy. Results: Anxiety-VAS and Stress-VAS were significantly lower after than before inhalation of clary sage oil (p< .01 and p< .05, respectively) and linalyl acetate (p< .05 and p< .05, respectively), despite having no significant difference in the three groups compared with control group. Systolic (p< .05) and diastolic (p< .01) blood pressure before undergoing chemotherapy were significantly lower after than before inhalation of linalyl acetate, while there was no significant difference in after than before inhalation of clary sage oil, despite both reducing levels of anxiety and stress. Conclusion: These findings suggest that linalyl acetate inhalation may be inappropriate in lowering anxiety and stress in patients undergoing chemotherapy, despite its anxiolytic and antistress effects, while clary sage oil inhalation may be useful in reducing anxiety and stress in patients undergoing chemotherapy, which has a risk of hypotensive side effects.

The effect of PHAR-DBH-Me, a cannabinoid receptor agonist, on different cardiovascular responses in adult male rats was analyzed. The blood pressure was measured directly and indirectly. The coronary flow was measured by Langendorff preparation, and vasomotor responses induced by PHAR-DBH-Me in aortic rings precontracted with phenylephrine (PHEN) were analyzed. The intravenous injection of the compound PHAR-DBH-Me (0.018-185 ㎍/kg) resulted in decreased blood pressure; maximum effect was observed at the dose of 1,850 ㎍/kg. A concentrationdependent increase in the coronary flow was observed in a Langendorff preparation. In the aortic rings, with and without endothelium, pre-contracted with PHEN (10^-6 M), the addition of PHAR-DBH-Me to the superfusion solution (10^-12-10^-5 M), produced a vasodilator response, which depends on the concentration and presence of the endothelium. L-NAME inhibited these effects. Addition of CB₁ receptor antagonist (AM 251) did not modify the response, while CB₂ receptor antagonist (AM630) decreased the potency of relaxation elicited by PHAR-DBH-Me. Indomethacin shifted the curve concentration-response to the left and produced an increase in the magnitude of the maximum endothelium dependent response to this compound. The maximum effect of PHAR-DBH-Me was observed with the concentration of 10^-5 M. These results show that PHAR-DBH-Me has a concentration-dependent and endothelium-dependent vasodilator effect through CB₂ receptor. This vasodilation is probably mediated by the synthesis/release of NO. On the other hand, it is suggested that PHAR-DBH-Me also induces the release of a vasoconstrictor prostanoid.

Objective: The purpose of this study is to investigate the effect of Cheonmagudeung-eum (CGE) for essential hypertension by systematic review and meta-analysis. Methods: The period of literature search was until October 30, 2016, and 14 electronic databases were utilized as search engines. The evaluation for the risk of bias (RoB) was conducted by using the Cochrane Risk of Bias Tool. The meta-analysis was performed by synthesizing outcome data, including total effective rate (TER), systolic blood pressure (SBP), diastolic blood pressure (DBP), and the incidence of adverse events. Result: There were a total of 64 RCTs using CGE on adult essential hypertension. In the RoB evaluation, most of the items were unclear, and the qualities of studies were rated low. The concurrent treatment of CGE and antihypertensive drug (AHD) showed a significant hypotensive effect since the risk ratio (RR) of TER was 1.17 times (95% CI 1.14, 1.20, p<0.01) higher than that of AHD alone. In addition, the mean difference (MD) appeared low as 8.73 mm/Hg in SBP (95% CI -11.36, -6.09, p<0.01) and 5.81 mm/Hg in DBP (95% CI -7.50, -4.12, p<0.01). Conclusion: Through this study, it was identified that the combined treatment of CGE and AHD on hypertension would be more effective than that of AHD treatment alone. However, due to the low quality of the selected original articles, the significance of this conclusion is somewhat limited, and we hope that this would be complemented through more rigorous RCTs in the future.
